Description
The utility model relates to a kind of automatic control pressure vent, be specifically in a kind of hot-water heating pipe-line system can self-bleeding valve.
Supply water and water heating system in, outlet valve is that water is unimpeded, one of the requisite facility of circulation Channel Group.Owe sensitive, easy water clock and keep in repair problems such as more miscellaneous at closing of domestic this series products existence, the inventor has proposed name, and to be called " quick-action outlet valve ", application number be 95207516.4 patent application, and the power of patenting, solved the problems referred to above basically.This technological scheme provides a kind of drain tap of sensitivity, leakage-proof and convenient for maintaining.Through practice, when finding the float motion of outlet valve, the problem of swinging that is occurred should solve, and Ying Lingqi only does necessary upper and lower motion, so that make outlet valve work more reliable, corresponding process structure also should further improve.
The purpose of this utility model is to provide a kind of outlet valve, and a kind of float of outlet valve is only made necessary upper and lower motion, the more rational automatic control pressure vent of process structure.
The purpose of this utility model is by being provided with and the fixing exhaust rubber cushion of pull bar, extension spring and spool, the translot of stretching float and the design realization of locating to be provided with stiffening rib on valve gap with the translot of float mutually.
Automatic control pressure vent of the present utility model, by valve body spare, workpiece, float and auxiliary are formed, and use the valve body of scyewed joint between comprising in the valve body spare, valve gap, bonnet ends disconnected valve body and seal ring, and bonnet is provided with vent; Workpiece comprises valve rod, exhaust rubber cushion, extension spring and pin hole; Float is provided with side channel, and translot and kerve, translot are provided with translot beam and stile, and side channel communicates with kerve, and the groove of translot is to perpendicular with the line of centres of two side channels, and the rear end of valve rod is under the translot beam; Auxiliary comprises seal ring, and valve block enters the hole, is subjected to the arm of force, is entering the hole and is being subjected to stage clip and seal groove between the arm of force; Wherein:, be provided with the spool with the valve gap scyewed joint, and be provided with seal ring at the front end of valve rod; Extension spring is fixed between valve rod and the spool, and pin hole passes spool; The exhaust rubber cushion is real core cylindrical body, is located at the ingress of pin hole, and fixes with valve rod; Between spool and bonnet, be provided with flat rubber cushion; Below spool, valve gap extends internally into stiffening rib; Seal groove is fixed in the lower end of valve block, is provided with seal ring in it.
As the further improvement of automatic control pressure vent of the present utility model, the stile of float translot and its groove are to parallel.
Automatic control pressure vent of the present utility model, its exhaust rubber cushion and flat rubber cushion are by silica gel, and nitrile butadiene rubber or rubber are made.
Automatic control pressure vent of the present utility model, its working principle is as described below: when not having gas in the outlet valve, valve rod only is subjected to the effect of extension spring, is in flat horizontal state, the tightly stifled pin hole of exhaust rubber cushion; When in the outlet valve gas being arranged, gas pressure forces float motion down mutually, thereby the translot beam of float presses down valve rod, leaves pin hole thereby drive the exhaust rubber cushion, and gas is discharged through exhaust port from pin hole, realizes the automatic vent function; When in case water leakage phenomenon appears in outlet valve, immediately bonnet is tightened, made flat rubber cushion block the pin hole outlet of spool, metal run out thereby stop, valve gap and valve body backed out keep in repair, at this moment, being subjected to the arm of force and advancing stage clip between the hole, will uphold, by its elastic force, seal groove is upwards drawn, will enter the hole until the seal ring of seal groove and block, stop into water; After maintenance is finished, valve body and valve gap be screwed into end disconnected valve body, simultaneously, the stage clip pressurized, seal groove is moved downward, and breaks away from into hole, the beginning normal water supply until the seal ring of seal groove.
The advantage of automatic control pressure vent of the present utility model: the valve gap place that matches with the translot of float is provided with stiffening rib, has strengthened the control to float, and it can not be vacillated now to the left, now to the right, and can only move up and down, thereby make automatic control pressure vent work more reliable; Adapt with establishing stiffening rib on the valve gap, the valve rod of workpiece, extension spring and spool technological design are more reasonable.
Below in conjunction with embodiment, automatic control pressure vent of the present utility model is described further.
Fig. 1 is the structural representation of automatic control pressure vent of the present utility model.
Fig. 2 is the structural representation of the utility model embodiment's float.
Fig. 3 is the plan structure schematic representation of the utility model embodiment's float.
Fig. 4 is the utility model embodiment's a valve block cross-sectional view.
Referring to Fig. 1-Fig. 4.
The utility model embodiment's automatic control pressure vent, by valve body spare, workpiece, float 5 and auxiliary are formed, and use the valve body 1 of scyewed joint between comprising in the valve body spare, valve gap 2, bonnet 3 ends disconnected valve body 4 and seal ring 10, and bonnet 3 is provided with vent 15; Workpiece comprises valve rod 6, exhaust rubber cushion 7, extension spring 8 and pin hole 12; Float 5 is provided with side channel 51, and translot 52 and kerve 54, translot 52 are provided with translot beam 53 and stile 55, and side channel 51 communicates with kerve 54, and the groove of translot 52 is to perpendicular with the line of centres of two side channels 51, and the rear end of valve rod 6 is under the translot beam 53; Auxiliary comprises seal ring 10, and valve block 14 enters hole 22, is subjected to the arm of force 23, is entering hole 22 and is being subjected to stage clip 24 and seal groove 25 between the arm of force 23; Wherein:, be provided with the spool 9 with the valve gap scyewed joint, and be provided with seal ring 10 at the front end of valve rod 6; Extension spring 8 is fixed between valve rod 6 and the spool 9, and pin hole 12 passes spool 9; Exhaust rubber cushion 7 is real core cylindrical body, is located at the ingress of pin hole 12, and fixing with valve rod 6; Between spool 9 and bonnet 3, be provided with flat rubber cushion 11; Below spool 9, valve gap 2 extends internally into stiffening rib 16; Seal groove 25 is fixed in the lower end of valve block 14, is provided with seal ring 10 in it.
The utility model embodiment's automatic control pressure vent, wherein the stile 55 of float 5 translots 52 and its groove are to parallel.
The utility model embodiment's automatic control pressure vent, exhaust rubber cushion 7 and flat rubber cushion 11 are made by nitrile butadiene rubber.
The utility model embodiment's automatic control pressure vent, during the outlet valve proper functioning, in case when in the outlet valve gas being arranged, gas pressure forces float 5 motion down mutually, thereby the translot beam 53 of float 5 presses down valve rod 6, drive exhaust rubber cushion 7 and leave pin hole 12, gas from pin hole 12 outside exhaust port 15 automatic discharge tubes; When not having gas, float 5 floats, and its translot beam 53 disengages with valve rod 6, and extension spring 8 allows valve rod 6 reset, and exhaust rubber cushion 7 is blocked pin hole 12 heavily again.
The characteristics of present embodiment are: because the stile 55 of the translot 52 of float 5 is stretching, and the place of matching is provided with stiffening rib 16 again with it on valve gap 2, enlarged the area of contact of float 5 with valve gap 2, strengthened motion control to float 5, overcome the wiggly shortcoming of float preferably, made outlet valve work more reliable.
